For Good Measure: Baking with Gluten-Free Blends, Whole Wheat Flour, Sourdough and at Challah Bakes

Once upon a time, baking a loaf of bread was simple. Today, when gluten-free blends and processed whole wheat flour are found in many homes, that is no longer the case. Baking with sourdough starters and group baking at “challah bakes” have also become popular. The halachos involved are complex and bear examination.

Let’s begin with a review of the measurements necessary for mitzvos related to regular wheat flour.[1]

Mitzvos Involving Wheat Flour

► Separating Challah (hafrashas challah) Without a Bracha – One should separate challah without a bracha when kneading a dough that contains at least 8 ⅔ cups of wheat flour (on average 2.6 lbs.).[2]

► Separating Challah With a Bracha – There are differences of opinion as to how much flour is needed to recite a bracha. Some individuals do so when kneading at least 12 ¼ cups of flour (slightly more […]

The Knead to Know: The Rise of Sourdough

By: Rabbi Tzvi Rosen

Fall 2023

We are all familiar with the Torah’s directive to rid our homes of chometz in order to prepare for Pesach. The Torah uses two terms when instructing us in the cleaning process: chometz and se’or.

Ask any talmid or talmida: “What is chometz,” and you will get a very erudite response. Ask the next question: “What is se’or,” and seven out of ten will shrug and say, “I dunno,” while the other three might venture, “Sourdough?” When you follow up and ask them to define sourdough, most – if not all – will say, “I dunno!”

Today, more and more homes are seeing sourdough boules find their way into their bread baskets. With its “rise” in popularity, it is only natural that we look into this new trend and ask, “Ma nishtana sourdough bread from its conventional counterpart? Are there halachic and practical differences?”

The Rise of Oat Matzos

By: Rabbi Moshe T. Schuchman

January 2025

The advent of baking oat matzah for Pesach is a relatively new phenomenon. As one of the Five Grains, oats qualify as an ingredient for matzah. Until circa 5740 (1980s), however, it never appeared in recorded halacha as something that was done in actual practice.

If someone with a wheat allergy can tolerate spelt, matzah made from spelt is an ideal alternative. Spelt and wheat are closely related both structurally and halachically. Additionally, some suggest that the order of grains in the Mishnah has significance. Thus, spelt, which appears third in the list, takes precedence over rye or oats. Others reject this notion and hold that position on the list does not indicate hierarchy for matzah.

What are the options for people who suffer from celiac disease, an inherited autoimmune disorder identified in the 1950s as being triggered by gliadin peptides (small proteins) in gluten? If the severity of the […]
